FIG. 10 is a view on arrow XX in FIG. 9. Safety cover 28 and mounting bracket 30 are gear cases
Protrusions 66 and 6 that protrude inward in the radial direction at the mating part with 18.
Have 8 each. The annular groove 62 is formed at the tip of the gear case 18, has a width larger than the thickness of the fitting portion of the safety cover 28 and the mounting bracket 30, and secures the safety cover 28 and the mounting bracket 30 in the axial direction of the gear case 18. It is adapted to be displaceably fitted over a range. A plurality of locking holes 64 are arranged in the axial direction and the circumferential direction of the gear case 18 in the bottom wall portion of the annular groove 62 so that the projections 66 and 68 of the safety cover 28 and the mounting bracket 30 can be fitted in the radial direction of the gear case 18. Has become. The positions of all the locking holes 64 are set so that the distance of the safety cover 28 from the cutting blade 20 becomes an appropriate value when the protrusions 66 and 68 are fitted. To change the position of the safety cover 28, change the position of the safety cover 28 and the protrusions 66, 68 of the mounting bracket 30.
After being fitted into desired locking holes 64 in the axial direction and the circumferential direction, the bolt 32 is tightened again, and the safety cover 28 and the mounting bracket 30 are fastened to the gear case 18. When the protrusions 66, 68 are fitted in the locking holes 64 of the annular groove 62, the safety cover 28 and the mounting bracket 30 are locked in the axial direction and the circumferential direction of the gear case 18. As a result, the safety cover 28 has an appropriate distance from the cutting blade 20 in the axial direction of the gear case 18, and then the bolts 32 are slightly loosened, so that the safety cover 28 and the mounting bracket are
Even if the gear 30 moves in the axial direction and the circumferential direction of the gear case 18, the locking holes 64 hold the positions of the safety cover 28 and the mounting bracket 30 in the axial direction and the circumferential direction by the locking of the protrusions 66 and 68.
